Because you cannot compare like with like. A masonic initiation is interesting and moving… (you can tell what is being stimulated). A magical one, done properly, hits every part of you.Masonic is more gentle and probably effective over a longer time. A magical initiation should be much more intense and its effects more sudden. It is difficult to describe if you have not been in a decent magical initiation. The book talks about how the GD started with a similar approach to masonry… then it became more magical. I think that it reached its height with Whare Ra and to a lesser extent with Brodie Innes’s AO.
